This system of governance was instituted on 28 June 1858, when, after the Indian Rebellion of 1857, the rule of the East India Company was transferred to the Crown in the person of Queen Victoria[18] (who, in 1876, was proclaimed Empress of India). It lasted until 1947, when the British Raj was partitioned into two sovereign dominion states: the Union of India (later the Republic of India) and Pakistan (later the Islamic Republic of Pakistan). Later, the People's Republic of Bangladesh gained independence from Pakistan. At the inception of the Raj in 1858, Lower Burma was already a part of British India; Upper Burma was added in 1886, and the resulting union, Burma, was administered as an autonomous province until 1937, when it became a separate British colony, gaining its own independence in 1948. It was renamed Myanmar in 1989. The Chief Commissioner's Province of Aden was also part of British India at the inception of the British Raj, and became a separate colony known as Aden Colony in 1937 as well.
